CVE-2020-10507
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe School Manage System before 2020, developed by ALLE INFORMATION CO., LTD., contains a vulnerability of Unrestricted file upload (RCE) , that would allow attackers to gain access in the hosting machine.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe School Manage System before 2020 contains an unrestricted file upload vulnerability that allows attackers to upload malicious files (such as web shells) to the server, leading to remote code execution. Attackers can exploit this to gain full access to the hosting machine.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm School Manage System installationCheck for the presence of School Manage System application files in the web server document root. Look for directories or files containing 'school' or 'schoolmanage' in the web root path.Affected if The application files are found in the web server's accessible directories.
-
Identify file upload endpointSearch the application source code or web directory for upload-related scripts, forms, or handlers. Look for file input fields and POST request handlers that process file uploads.Affected if A file upload feature exists and is accessible via the web interface.
-
Check file type validationExamine the upload handler code for server-side validation of file types. Look for whitelisting or content-checking logic before file storage.Affected if No server-side file type validation exists, or validation can be easily bypassed.
-
Verify upload storage locationCheck where uploaded files are stored relative to the web root. Look for upload directories inside publicly accessible web paths.Affected if Uploaded files are stored within the web-accessible directory structure.
-
Check script execution settingsInspect the web server configuration for the upload directory. Determine if script execution is permitted for files in the upload storage location.Affected if The upload directory allows execution of uploaded file types (e.g., PHP, JSP, ASP files can be executed).
If the School Manage System is installed with an accessible file upload feature that lacks proper validation, stores files in web-accessible locations, and permits script execution, the environment is affected by CVE-2020-10507.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict file upload validation including file type whitelisting, file content analysis, renaming uploaded files, storing uploads outside the webroot, and disabling script execution in upload directories.
